  1. PEFAPhysical Energy Flow Accounts ESTP Training Course Vienna, 29-30 April 2014

  2. 1 Introduction • Test data collection 2014 (May) – as agreed at Working Group meeting • Electronic PEFA questionnaire (related to legal act) • 5 Tables • Reduced number of rows and columns • IT-tool (‘PEFA-builder’) • Voluntary use • Processes IES/Eurostat Annual Questionnaires • More detailed rows and columns • Populates automatically the PEFA-questionnaire

  3. PEFA Table D “indicators” PEFA Table E “Bridge” Eurostat Energy Balance PEFA Table A “Supply” Table B “Use” Eurostat COMEXT Energy database IT tool “PEFA-builder” export csv additional/complementary tables (resident adjustment, industry detailing) IEA/ESTAT 5 Joint Questionnaires national energy balances national energy data

  9. 3 PEFA Questionnaire

  10. 4 General Compilation Guidelines • 4.1 Data sources • National energy statistics • Data sources for resident adjustments • Data sources for industry detailing • 4.2 Important conventions • Resident adjustments • Stock changes • Primary versus secondary products • Three compilation steps (suggested)

  11. 4.3 Supply of ‘primary’ energy products • …and their corresponding natural inputs • …and corresponding possible residuals (losses during extraction)
